Multiplying and dividing decimals is a lot like regular numbers, but the key is where you place the decimal point. Making a guess before you calculate can be handy. For example, if you multiply 2.3 by 4.01, you know the answer is around 9, not 92,000! Even better, learn the rules for decimal points in multiplication and division – it makes solving problems a breeze.
In the quiz below, try estimating your answers before diving into calculations – it'll help! Best of luck with your KS3 Maths journey!
